Create ansible playbook to run bt-0000-0001

[ShyamsundarR]

Currently the bench test provided in bt-0000-0001 is expected to be run by hand. We need to convert this into an ansible playbook, for more generic use.

Changes to the script that are needed for this to happen are as follows,

• [ ] Environment variable CLIENT_LIST needs to be passed in as an argument
• [ ] Environment variable SERVER_LIST needs to be passed in as an argument
• [ ] Install IOZone using a play rather than using python code as is now (issue #25)
• [ ] Install smallfile tools using a play rather than using python code as is now
• [ ] Remove the dependency that the script is run from one of the clients, IOW use a jump host of sorts to run the test on the actual setup, not from the host running the ansible play
• [ ] Transfer clients.ioz file to the junm host running the test
• [ ] Determine how to show progress when this is running via ansible
• [ ] Improve report to state KB/s or MB/s like qualifications for the numbers generated
• [ ] more to follow...

CLIENT_LIST could be play_hosts[:1] (all servers in the current run except the first) thus making SERVER_LIST to play_host[1]
